Depending on your injury, you may ski, or grab a camera and start filming friends while you heal. At least you get to be on the slopes and there is very little danger to filming, unless going switch or following a line of jumps. I've skied with a broken thumb for 10 weeks, sprained ankle, torn ACs, concussions, (these were not all at the same time, but some overlapped others) Be careful if you do park or film.
